Method for preparing artificial lightweight aggregate from oil sludge pyrolysis residues
The invention discloses a method for preparing artificial lightweight aggregate by utilizing oil sludge pyrolysis residues, and relates to an innocent treatment method and a resource utilization process of the oil sludge pyrolysis residues. The invention aims to effectively realize harmless and resource utilization of oil sludge pyrolysis residues generated in the exploitation process of resources such as petroleum, shale gas and the like. The method comprises the following steps: 1, preparing pellets with the particle size of 5-20mm by using the oil sludge pyrolysis residue as a raw material through a disc pelletizer; 2, carrying out air-drying maintenance on the obtained pellets; and 3, roasting the cured and dried pellets to prepare the artificial lightweight aggregate. The process is simple and easy to implement, the cylinder compressive strength, the water absorption rate, the stacking density and the boiling heat loss of the lightweight aggregate prepared by the method all meet the GB/T 17431.1-2010 artificial lightweight aggregate standard, and the lightweight aggregate can be widely applied to materials such as concrete and highway subgrade.
本发明公开了一种利用油泥热解残渣制备人造轻集料的方法，它涉及一种油泥热解残渣无害化处理方法和资源化利用工艺。本发明的目的是为了有效解决石油、页岩气等资源开采过程中所产生的油泥热解残渣的无害化和资源化利用。其方法包括：1.以油泥热解残渣为原料，通过圆盘造球机制备粒径为5‑20mm的球粒；2将所得的球粒进行风干养护；3将养护干燥后的球粒进行焙烧制备人造轻集料。该工艺简单易行，采用本发明制备出的轻集料的筒压强度、吸水率、堆积密度、煮沸热损失均满足GB/T 17431.1‑2010人造轻集料标准，可广泛用于混凝土、公路路基等材料。
